Objectives/Interrogation: To investigate the results of surgery on foot macrodactyly who underwent ray amputation.

Methods: 16 feet of 15 patients were included in the study. We radiologically measured the intermetatarsal width and forefoot area pre-operatively and at six weeks and two years after surgery. Clinical results were recorded using the Oxford Ankle Foot Questionnaire for children (OxAFQ-C) and the Questionnaire for Foot Macrodactyly.

Results and Conclusions: Mean follow-up was 49 months. The intermetatarsal width and forefoot area ratios were significantly decreased after surgery. The mean OxAFQ-C score was 35 (16 to 60) pre-operatively, improving to 48 (5 to 60) at two years post-operatively (p<0.05). The mean questionnaire for foot macrodactyly score two years after surgery was 8 (6 to 10). In conclusion, reduction in foot size with excellent functional results were achieved using ray amputation. For patients with metatarsal involvement, a motionless toe, or involvement of multiple digits, ray amputation is a clinically effective option.
